A dynamic load shedding scheme for maintaining system frequency stability with the increasing renewable energy penetration

Herath BHMST [Thesis-Abstract]

Renewable energy power plants, especially grid connected solar and wind generation units are displacing the conventional generator stations with rotating machines with inertia. In Sri Lanka, renewable energy generation has ...
Application of sensor network in locating moving trains for rail gate security system

Perera, WDSP [Thesis-Abstract]

This research project is designed for rail gate security system for vehicles and pedestrian. Currently, the railway system of Sri Lanka does not have a correct system to monitor and indicate correct positions of trains. ...
Assessment of embedded energy of floor tiles manufactured in Sri Lanka

Wijerathna, WMNK [Thesis-Full-text]

Floor tile manufacturing is one of the highest energy intensive industries in the world. Basically, the thermal energy is the most prominent energy component in the value. Embedded energy is a fairly a new concept which ...
Asset management of aging devices in energy systems based on probabilistic modelling : a case study on diesel engines

Pathirana NPDS [Thesis-Full-text]

The purpose of maintenance is to lengthen the equipment lifetime. Too little maintenance may have costly consequences; whereas too frequent maintenance may not be economical. Hence the two costs, i.e. the cost of failures ...
Benchmarking of electricity distribution licensees operating in sri lanka

Neelawala, L [Thesis-Abstract]

Electricity sector regulators are practicing benchmarking of electricity distribution companies to regulate allowed revenue to each company. Mainly this is done by using the relative efficiency scores produced by frontier ...
Capacitor switching transient analysis on a transmission grid substation (case study : Thulhiriya GSS)

Munasinghe, DLP [Thesis-Full-text]

The quality of electric power system has a great concern and also it has been a constant topic of study. A transient originated from capacitor bank switching are main reason which affects the power quality. The analysis, ...
Condition monitoring and assessment of power transformers using sweep frequency response analysis and dissolve gas analysis.

Fernando, MPM [Thesis-Full-text]

Power transformer can be considered as the key element in an electricity power system. Cost and the time of installation of a power transformer are significantly higher than the installation of other equipment. Applied ...
Consideration of losses in determining solar PV penetration level in distribution networks

Nishshanka RMMP [Thesis-Abstract]

When it was realized that the conventional energy sources which powered up the industrial revolution are on depletion, a sudden awakening occurred in the field of renewable energy, during the latter part of the last century. ...
A Cost optimization methodology for design of substation earthing system

Gunaratne DPCTW [Thesis-Abstract]

Current practice for earthing grid design for AC substations is mainly guided by IEEE 80 ; 2000 standard. This practice is an iterative process of changing design variables until safety requirments for step and touch ...
Criteria for selecting LED luminaires

Chamari RML [Thesis-Abstract]

Fluorescent tubes and compact fluorescent lamps (CFL) were the dominant artificial light source for so many years in domestic, commercial and industrial contexts. In the recent years Light Emitting Diodes (LEDs) have gained ...
Design a contingency electricity feeding plan a case study : Dehiwala area

Kumara, GKA [Thesis-Full-text]

CEB is mainly Electricity Generating, Distributing and solely Electricity Transmitting organization in Sri Lanka. Few years back, main target of CEB was to achieve 100% electrification level and was not greatly concerned ...
Design a DSM oriented, time of use (TOU) tariff model for domestic consumers with a load research

Udageachchi EH [Thesis-Abstract]

The night-time peak demand drives the sector investments and hence has become a major target area for Demand Side Management programs aimed at energy conservation and efficiency improvement. Time Of Use (TOU) Tariffs are ...
Designing a prototype vortex induced vibrations based hydroelectricity generating system

Warakaulla WHMPM [Thesis-Full-text]

With the inevitable concerns on energy crisis and environmental pollution, various types of alternative energy resources such as, hydro, wind, solar, tidal, wave, etc.,havebeen harnessed using various novel technologies. ...
Designing an earth electrode for distribution substations

Samarasekara, PPB [Thesis-Full-text]

In electrical engineering, the term ground or earth has several meanings depending on the specific application areas. Ground is the reference point in an electrical circuit from which other voltages are measured, a common ...
Designing earthing system for distribution transformers in high resistive soils at restricted areas

Fernando, AHGR [Thesis-Full-text]

Earthing of Distribution Transformer is very important in the sense of safety and protection of human beings, livestock and equipment. The construction personals have faced critical issues on earthing when they engage in ...
Determination of maximum possible loading capacity of a single generator unit : a case study for the present Sri Lankan power system

Ranjitha, RS [Thesis-Full-text]

Present Sri Lankan power system consists of a rich energy mix and a vast diversity within all over the island, out of which hydro power generation is predominant. Even though hydro power generation is predominant and has ...
Development of a generalized methodology for blackout restoration : a case study of Sri Lankan power system

Sirisena, KLU [Thesis-Full-text]

Blackouts are been reported throughout the history worldwide and nowadays, a moment without electricity causes a greater loss of lives and economy. On the other hand, restoration of a blacked-out power system requires ...
Development of a guideline for designing economical and effective retrofit led street lighting system for Sri Lanka

Muthuransi LWN [Thesis-Abstract]

Nowadays most of the conventional type street lights are been converting to LEDs (Light Emitting Diodes). But there are no proper criteria or standardize methods to replace these conventional type street lamps to LEDs. ...
Development of an electric spring for voltage management in LV network as a consumer level solution

Hafeel AA [Thesis-Abstract]

LV consumers are encouraged to invest on roof top solar and wind turbines to reduce the stress on the utility side. Due to the intermittent nature of these distributed generators the stability of the power system and the ...
Development of hybrid islanding detection technique for distributed power generation

Tilakeratne, RP [Thesis-Full-text]

The utilization of distributed generation (DG) units is rapidly increasing in power system and questions are raised regarding their effect on the system, energy management and protection policies. DG can provide in some ...
